p.1 #1 · The light torture of choice - M-mount lenses


Hi,

How is everyone doing? I hope very well : )!!!

I am looking for an M-mount wide angle lens.

Perhaps you have heard a phrase similar to the
one in the title of this thread: a light torture of
(sometimes too much) choice : )!!! A phrase that
at the moment makes me happy about it, because
it sends me lens searching/researching : )!!!

I may be getting a voigtländer lens, a 28mm or
35mm lens. I just don't know where to get a bit
more information about their lenses.

Each lens model has at least two different versions
of it on the market.

I would like to take a closer look at the noctons, the
ultrons, and the color-skopars.

I would appreciate any advice on how to approach
this (re)search.

Thank you in advance, kind regards,

Arurso : )!!!

Right here on this board is a great resource: Fred's tests of pretty much all of these lenses.

In a nutshell, from Voigtlander at 28mm you span f/1.5 to f/2.8. IIRC, these are all pretty consistently similar lenses - very good overall sharpness, contrast, etc. There will also be a 28/2 APO coming in the near future. You just decide on how much speed you need, whether size and weight are considerations, etc.

At 35mm there are more options and also 'character' lenses in the mix, like the 35/1.4 'classic' and perhaps also the 35/1.2, though it's a different, more modern 'character' lens. Otherwise you can get optical near perfection/sharpness from the 35/2 APO. Similar to 28mm, there is an even greater range of speeds to choose from: f/1.2, 1.5, 2.0, 2.5, 3.5...

p.1 #3 · The light torture of choice - M-mount lenses


I personally find 35 mm a great all-rounder small wide angle lens on my M cameras. I also own 28 mm based M lenses but use them less. One trap to get easily stuck in is to strive for the fastest lens - IMO it is most of the time not necessary to have a wider lens faster than f/2.0 especially when rarely using it in low light conditions - the lens only gets heavier and sometimes bulkier. IMO the best compromise regarding lens speed is between f/2.0 and f/2.8 with rangefinder usage. I became a fan of the more affordable but unfortunately no longer made Leica 35/2.4 ASPH Summarit-M lens.

I agree with this entirely. And I ended up with a CV 35/2 ultron for the same reasons. I purchased one at launch and have been using it pretty consistently through throughout. Tried a couple different copies, but ended up liking v1

The light cine world is going through this lens speed issue, also. Even in the mainstream high end, the fast lenses are really highly valued, along with close focus. The makers have, at long last, rediscovered the long venerated 28mm focal length as the entry level wide lens angle of view.

The CV 28/1.5 weighs 250 grams (type I). Let me put the fast wide angle case to you, despite knowing nothing of what you might intend to use it for. All things being equal enough - weight, bulk, cost - you have one to two precious stops more available to you, with no loss in mid and small aperture performance. Done well, you have two lenses in one. All CV's 28s are of similar complexity, all use small filters.

And the bonus is not merely a little more DOF control. You get an entirely new look, by design because all f1.5 lenses are made for wide open use. 28s have a particular view on the world that lends itself to fast max apertures because they arrange the seen objects in image space more effectively than 35mm lenses, yet they do not convey that stereotypical wide angle AOV, which is harder to work with.

And it is a look not seen by any but very cashed up users in the recent past, within the M ecosystem. Most 28 users ended up associating 28s with landscapes and light urban use only.

The combination of progressive bokeh and high vignette, and shooting subjects at longer working distances..this is alluring and can be addictive, for say, city streets and people - the arty look if you will. The best part is that 28s are easy to produce to a high standard of performance. It's a universal focal length, used in many fixed lens cameras. 35s and 40s encroach on 50mm, in this context above. 28s can also be used ~a stop wider for the same DOF as a 35mm. It is such a useful focal length that many lens producers did not make any of them for many years. Now they are everywhere.

Yes, some months ago, I was able to see Fred's reviews for the 28mm Ultron and the 28mm Color-Skopar. Those two lenses are amazing! From the reviews, I don't know why, but between those two I started to lean more towards the Color-Skopar, when the Color-Skopar, seems to me, is generally the less regarded of the two lenses.

I would like to see a review for the 28mm Apo-Lanthar. As soon as Fred reviews it, I'll take a look at it to have an idea of this lens in general.

I had not seen Philli Preeve's reviews. Lately, I stumbled upon Jack Takahashi's review of the 28mm Nokton. I liked his review. I'll also start to read Philli's reviews.

Here is a link to Takahashi: https://jacktaka.com/voigtlander-28mm-f15

Yes, I have seen that, mainly in some very luminous rangefinder lenses from Leica. Also in some Voigtländer lenses, like the Apo-Lanthars, in their 35mm. and 50mm. versions. That's why I would like to take a closer look at the 'compactness' of the 28mm. Apo-Lanthar when it comes out. Otherwise, due to their more compact price and price, the Ultron and Color-Skopar, are more attractive.

Yes, the Summarits, in focal lengths of 35, 50, and 75mm. are very nice. Compact and their price is also more affordable. Really a shame that they stopped making them. I hope they make them again some day. I liked both their f/2.4 and f/2.5 versions.

Yes, as soon as I get the lens, it will almost be glued to the camera : )!!! I'll be using most of the time!

About a bit over a month, B&H was out of stock of the Ultron and the Color-Skopar in 28mm. focal length. So, I started to look at what they had in stock, and it was the Nokton 28mm. f/1.5 lens. I started to look for information about it and photos made with it. It is a very nice lens. The pictures made with it, one can see some in Takahashi's link, (above), and in the ones from internet searches, and one will see that this lens has as much muscle as the Ultron and the Color-Skopar, and perhaps a bit more.

Yes, in spite that it costs more than the Ultron and the Color-Skopar, I am considering it.

Thank you again for all your messages : )!!!

p.1 #7 · The light torture of choice - M-mount lenses


For the basic specs on all the Voigtlander Leica M mount lenses here is the Japanese site for the Voigtlander lenses:

https://www.cosina.co.jp/voigtlander/en/vm-mount/

My take is that all the 28mm lens perform quite well and are small for what they are. They make an f/1.5, f/2.0, & f/2.8 and an f/2.0 APO will be available for the first time next month. I think the available lenses share a common look and common weaknesses. They all are quite sharp and sharp across the frame, they all are pretty resistant to flare, they all produce nice colors, but they all are a bit prone to purple fringing, they all have pretty high vignetting which can affect the bokeh, and have only modest to moderate control of axial chromatic aberration. The new f/2 APO will likely have a different profile with even better sharpness, little to no purple fringing, and little to no axial CA. I would pick based on what size and speed you think suits the type of shooting you do. If you shoot a lot of street photography at night, the f/1.5 is a solid choice and still quite small. If you shoot during pretty bright light out of doors then the f/2.8 would probably serve all your needs. The f/2.0 is a solid middle ground choice and the new f/2 APO might well turn out to be the best of the bunch for a lot of shooters.

At 35mm they have these same basic options plus a few more thrown in and instead of an f/2.8 they have an f/2.5 and an f/3.5. In addition they have an f/1.4 that is very small and produces a very different look reminiscent of lenses from an earlier era with a softer rendering, more glow and more outlining in the bokeh. They also have an f/1.2 that has a more modern rendering and is a bit larger. They no longer make it, but their 35 f/1.7 is also an interesting lens that many people like--I like the optical performance of this lens a lot but not the ergonomics.

Fred's reviews are great for these lenses and here are some links to lenses he has reviewed:

28mm lenses

28 f/1.5 https://www.fredmiranda.com/forum/topic/1842505/
28 f/2 https://www.fredmiranda.com/forum/topic/1704868/
28 f/2.8 https://www.fredmiranda.com/forum/topic/1819458/

35mm lenses

35 f/1.2 (with the recent 40 f/1.2 and 50 f/1.2) https://www.fredmiranda.com/forum/topic/1904365/
35 f/1.5 https://www.fredmiranda.com/forum/topic/1784972/
35 f/2 APO https://www.fredmiranda.com/forum/topic/1695782/
35 f/3.5 https://www.fredmiranda.com/forum/topic/1868807/

That is a pretty comprehensive set of reviews, but of course there aren't any reviews of the 28 f/2 APO that is coming out next month. In addition Fred hasn't done reviews of the 35 f/2 non-APO version, the 35 f/1.4 classic, the 35 f/2.5 or the 35 f/1.7. There are threads about each of these 35mm lenses for which Fred does not have reviews, however, so you might want to wade through those threads if one of them really piques your interest.

If it is possible for you to do so, renting one or two for a weekend can clarify things way better than any review or video. Unless you are obsessively pixel-peeping many of the 'usual suspects' are optically quite similar, and things that are drawbacks or 'trouble' for some you may not even notice. Other issues of form-factor, particularities of how you personally shoot in terms of style, content, etc, may be deal-breakers for you that no review would consider. No better way than to have it in the hands, shoot, and see what you get. Not to introduce another element of choice, but you might also consider 24mm depending on what you mean by wide-angle. 35mm is wide-ish, but closer to the eye than many realize. 28mm and 24mm feel much more encompassing of what's in front of you, drawing in the foreground and accentuating things like tilt and exaggeration of elements along the z-axis. They also necessitate moving much closer to your subjects depending on what you shoot, so may affect your style in ways that only using them can really hammer home.

Highly unlikely that Leica will bring them back. They caused three issues for Leica - the official reason from Leica is that they didn't meet their sales expectation (if true and following this logic, the SL series should have been taken off the market a while ago, too). But IMO the two main reasons are others: that the Summarit lens line simply didn't fit with their pricing to the luxury branding of Leica, and that they actually competed quite successfully in-house with more expensive f/2.0 lens versions in similar focal lengths especially for 35 and 50 mm. That Summarit lenses are in demand can be seen in used lens prices now - they actually increased since the lenses are no longer made by Leica.

If I remember correctly, the Summarit line was also developed by Karbe at Leica who once also stated that this lens line perfectionated lens speed, compactness, and quality. I can second this from my experience with the 35/2.4 ASPH lens.

Lots of choices in the 28 and 35 mm range for M lenses including now options from Voigtlander, Zeiss, TTArtisan, 7Artisans and a few other Chinese ones. They all have their little pros and cons, and it is likely an endless iteration of weighing options when comparing them in detail. In the end I would go for what is available for a good price at personally suitable lens size and lens speed. Nobody ever asked me which kind of lens I used when just seeing a photo which I took at 35 or 50 mm focal length. We lens nerds might look into bokeh structure details etc but no regular viewer of a photo will pay much if any attention to it. The composition is all it matters.
